Description

Technical Field

[0001] The invention relates to the technical field of self-generating hydraulic systems, in particular to a self-generating hydraulic system for a wireless remote-controlled grab bucket. Background Art

[0002] In many industrial equipment and mechanical systems, hydraulic systems play an extremely critical role. As the core control component of the hydraulic system, the hydraulic valve block has the main function of accurately regulating the flow of hydraulic oil to achieve various complex mechanical movements. When the wireless remote control grab device is working, the hydraulic system first gives the operation great convenience and safety. The operator can remotely control the grab by wireless remote control, stay away from dangerous working areas, and accurately control the opening and closing, lifting and rotating of the grab, just like accurately grabbing containers at the port. Secondly, the grab is driven forcefully. The hydraulic oil is pressurized by the pump, valve-controlled and cylinder-driven, so that the grab can grasp the bulk cargo steadily and lift and lower accurately. If there is a rotation function, it can also turn flexibly to meet different unloading needs. Furthermore, the grab is guaranteed to be stable and reliable, automatically adjust the pressure and flow according to the load, and adapt to light and heavy cargo. High-quality components ensure sealing and stability, and reduce downtime due to failures. Finally, the operating efficiency and accuracy are greatly improved, precise control is carried out to prevent cargo from being scattered and damaged, and rapid response helps to load and unload more per unit time, increase efficiency and reduce losses.

[0003] The hydraulic valve block in the prior art only focuses on the control task of hydraulic oil and does not have the function of self-generating electricity. In the scenario where power supply is inconvenient or impossible, the system cannot work normally. However, during the operation of the hydraulic system, the hydraulic oil flows at high speed in the valve block channel, carrying a large amount of kinetic energy and pressure energy. These energies are usually wasted in the form of heat loss inside the system, and are not effectively recovered and reused. In addition, during the operation of the hydraulic system, although the hydraulic oil tank has a built-in filtering device, it does not take into account the harm caused by the hydraulic oil driving the impurities inside the pipeline and the tank to move rapidly inside the pipeline and other devices, and how to filter and treat the impurities. The high-speed flowing impurities frequently hit the precise valve core, valve seat and channel wall inside, which can easily cause surface scratches and wear, damage the sealing of the valve block, cause internal leakage, reduce the system pressure control accuracy, and affect the accuracy of the grab action. There is a lack of an effective mechanism for filtering and treating impurities. Impurities will continue to accumulate in the system, aggravating the risk of pipeline blockage and increasing the flow resistance of the oil. Not only does it increase energy consumption, it may also cause overload damage to the oil pump, shorten the life of the entire hydraulic system, and frequently repair and replace parts.

[0004] Therefore, the present invention provides a self-generating hydraulic system for a wireless remote-controlled grab bucket, which can convert the kinetic energy and pressure energy carried by hydraulic oil into electrical energy and can filter and process impurities in the hydraulic oil. Summary of the invention

[0005] In view of the fact that a large amount of kinetic energy and pressure energy carried by hydraulic oil in the prior art is wasted, and the harm caused by the rapid movement of impurities in pipelines and oil tanks driven by hydraulic oil and how to filter and deal with impurities are not taken into consideration, a self-generating hydraulic system for a wireless remote-controlled grab is designed.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Example: Figures 1 to 10As shown, a self-generating hydraulic system for a wireless remote control grab comprises a base 1, a housing 2 is fixed on the top of the base 1, a protective shell 3 is fixed on the top of the base 1, the housing 2 is located on one side of the protective shell 3, a turbine 4 is rotatably connected to the inner side of the base 1, a generator 5 is arranged on the top of the turbine 4, a main gear 6 is fixed to the rotating shaft of the generator 5, a clutch 7 is arranged on one side of the main gear 6, a connecting member 79 is arranged on the inner side of the clutch 7, a transmission member 8 is arranged on the side of the clutch 7 close to the main gear 6, a moving plate 10 is fixed on one side of the transmission member 8, and the inner side of the moving plate 10 is slidably connected to the inner side of the moving plate 10. There is a filter plate 9; a clutch 7, which is assembled to cooperate with the main gear 6 through a connecting member 79 to drive the transmission member 8 to move; the connecting member 79 is assembled to separate or realize the power transmission of the clutch 7 and the transmission member 8; the transmission member 8 is assembled to drive the movable plate 10 and the filter plate 9 to move, and a groove is opened through the top of the base 1, and a round rod 13 is fixed on the inner side of the groove. The movable plate 10 is slidably connected to the outer side of the round rod 13, and a limiting plate 11 is fixed on the inner side of the groove. The top of the limiting plate 11 is detachably connected to a cover plate 12, and the filter plate 9 can be replaced by removing the cover plate 12.

[0032] In this embodiment, the staff connects this device in series in the hydraulic oil pipeline, and electrically connects the generator 5 with the energy storage device inside the grab bucket (such as a battery, which is a prior art and will not be described in detail). The hydraulic oil flows into the hydraulic oil channel from the oil inlet end close to the casing 2, and the turbine 4 blades can rotate efficiently under the impact of the hydraulic oil. The rotating shaft is rigidly connected to the turbine 4 blades to ensure that the rotating shaft can rotate flexibly and stably. The generator 5 is coaxially connected to the rotating shaft. When the turbine 4 blades drive the rotating shaft to rotate under the reciprocating push of the hydraulic oil, the generator 5 can convert the mechanical energy of the rotating shaft into electrical energy, and the generated electrical energy is stored in the energy storage device inside the grab bucket for subsequent use.

[0033] When supplying oil to the grab bucket, the turbine 4 blades drive the rotating shaft to reverse, the movable plate 10 and the filter plate 9 move into the inner side of the limiting plate 11, and the impurities in the hydraulic oil are filtered by the filter plate 9 to reduce the viscosity of the hydraulic oil; when the hydraulic oil is extracted from the grab bucket, the turbine 4 blades drive the rotating shaft to rotate forward, and the movable plate 10 and the filter plate 9 move out of the inner side of the limiting plate 11 and then return to their original positions. In the process of the filter plate 9 moving out of the limiting plate 11, the hydraulic oil reversely flushes the impurities filtered by the filter plate 9, and at the same time, the inner wall of the base 1 scrapes off the impurities on the surface of the filter plate 9, and finally rushes into the hydraulic oil tank with the hydraulic oil for filtering.

[0034] Specifically, the clutch member 7 includes a bracket 1 71 and a bracket 2 72. The bracket 2 72 is fixed to the top of the bottom wall of the casing 2, and the bracket 1 71 is fixed to the top of the bracket 2 72. Two groups of pillars 73 are fixed on the side of the bracket 1 71 close to the main gear 6, and the two pillars 73 form a group. A tooth plate 1 74 is slidably engaged with the inner side of the bracket 1 71, and the tooth plate 1 74 meshes with the main gear 6. A group of limiting rods 76 are fixed on both sides of the tooth plate 1 74, and the two limiting rods 76 form a group. The outer side of each group of limiting rods 76 is slidably connected with a movable plate 75, and a spring is fixed on the side of each movable plate 75 close to the limiting rod 76, and the other end of the spring is fixedly connected to the tooth plate 1 74. Baffles 77 are fixed on the top and bottom of the movable plate 75, and the baffle 77 contacts one of the groups of limiting rods 76. The tooth plate 2 78 is slidably engaged with the inner side of the bracket 2 72.

[0035] In this embodiment, the turbine 4 blades drive the rotating shaft to reverse, and the rotating shaft drives the main gear 6 to reverse, and the movable plate 75 moves to the side close to the main gear 6 and then meshes with the main gear 6 again. The main gear 6 drives the movable plate 75 to move to the side close to the protective shell 3 through the meshing action, and the movable plate 75 drives the tooth plate 1 74 to move to the end close to the protective shell 3 through the limiting rod 76, and finally the tooth plate 1 74 and the main gear 6 are meshed. The main gear 6 drives the tooth plate 1 74 and another set of limiting rods 76 and another movable plate 75 to move to the end close to the protective shell 3 through the meshing action. When the baffle 77 is fitted with the other set of pillars 73, the main gear 6 pushes the other movable plate 75 to squeeze the spring along the limiting rod 76 on its inner side to move to the side close to the tooth plate 1 74. When the main gear 6 is disengaged from the movable plate 75, the spring pushes the movable plate 75 to move to the side close to the main gear 6. At this time, the tooth plate 1 74 and the tooth plate 2 78 are separated, and only the tooth plate 1 74 moves.

[0036] Specifically, the connecting member 79 includes a link plate 791, which is fixed to one end of the tooth plate close to the main gear 6. A through hole 792 is penetrated through one side of the link plate 791. A telescopic rod 793 is fixed to the top of the bottom wall of the through hole 792. A three-plug plate 794 is fixed to the top of the output end of the telescopic rod 793. The three-plug plate 794 is located at the bottom of the baffle 77.

[0037] In this embodiment, the oil viscosity sensor is electrically connected to the external processor. When the oil viscosity sensor detects that the viscosity of the hydraulic oil increases, the oil viscosity sensor transmits a signal to the controller. Then, when the tooth plate 1 74 and the tooth plate 2 78 return to their original positions and the hydraulic oil is no longer flowing, the controller controls the output end of the telescopic rod 793 to extend, and the output end drives the three-plug plate 794 to move toward the side close to the baffle 77. The middle end of the three-plug plate 794 moves into the inner side of the baffle 77 of the tooth plate 1 74, and the other two ends of the three-plug plate 794 clamp the baffle 77 to the inner side of the three-plug plate 794, thereby connecting the tooth plate 1 74 and the tooth plate 2 78 together to realize the transmission of the tooth plate 1 74 and the tooth plate 2 78.

[0038] Specifically, the transmission member 8 includes a fixed shaft 81, which is fixed to the top of the bottom wall of the casing 2. The outside of the fixed shaft 81 is rotatably connected to a hollow rod 82, one end of the hollow rod 82 is fixedly connected to one of the pulleys 83, and the other end of the hollow rod 82 is fixed to a slave gear 84. The transmission member 8 also includes a transmission rod 86, which passes through and is rotatably connected to the top of the base 1, another pulley 83 is fixed to the top of the transmission rod 86, and the inner sides of the two pulleys 83 are sleeved with a belt 85. The other end of the transmission rod 86 is fixed with a bevel gear 1 861, and the inner side of the base 1 is rotatably connected to a threaded rod 87, and one end of the threaded rod 87 close to the transmission rod 86 is fixed with a bevel gear 2 871, and the bevel gear 1 861 and the bevel gear 2 871 are meshed. The transmission member 8 also includes a meshing plate 88, which is threadedly connected to the outer side of the threaded rod 87, and the meshing plate 88 is slidably connected to the outer side of the round rod 13.

[0039] In this embodiment, when the turbine 4 blades drive the rotating shaft to reverse, the tooth plate 1 74 drives the tooth plate 2 78 to move to the side away from the protective shell 3, the tooth plate 2 78 drives the hollow rod 82 to reverse, the hollow rod 82 drives the pulley 83 on its outer side to reverse, the pulley 83 on the outer side of the hollow rod 82 drives another pulley 83 to reverse through the belt 85, the other pulley 83 drives the transmission rod 86 to reverse, the transmission rod 86 drives the threaded rod 87 to reverse through the bevel gear 1 861 and the bevel gear 2 871, the threaded rod 87 drives the meshing plate 88 to move to the side close to the limiting plate 11 through the meshing action, the round rod 13 prevents the meshing plate 88 from shaking when moving, and the meshing plate 88 drives the moving plate 10 and the filter plate 9 to move into the inner side of the limiting plate 11;

[0040] When the blades of the turbine 4 drive the rotating shaft to rotate forward, the tooth plate 1 74 drives the tooth plate 2 78 to move toward the side close to the protective shell 3, the tooth plate 2 78 drives the hollow rod 82 to rotate forward, the hollow rod 82 drives the pulley 83 on its outer side to rotate forward, the pulley 83 on the outer side of the hollow rod 82 drives another pulley 83 to rotate forward through the belt 85, the other pulley 83 drives the transmission rod 86 to rotate forward, the transmission rod 86 drives the threaded rod 87 to rotate forward through the bevel gear 1 861 and the bevel gear 2 871, the threaded rod 87 drives the meshing plate 88 to move toward the side away from the limiting plate 11 through the meshing action, the meshing plate 88 drives the movable plate 10 and the filter plate 9 to move out of the inner side of the limiting plate 11 and then return to their original position.

[0041] Specifically, the movable plate 10 is fixed to one side of the engaging plate 88 , and circular holes 101 are formed through both sides of the movable plate 10 .

[0042] In this embodiment, when the side of the movable plate 10 away from the meshing plate 88 is in contact with the side of the limiting plate 11 away from the meshing plate 88, the hydraulic oil is discharged through the circular hole 101 to prevent the hydraulic oil from squeezing the movable plate 10 and causing energy waste of the generator 5.

[0043] Working principle: The staff connects this device in series in the hydraulic oil pipeline, electrically connects the generator 5 with the energy storage device inside the grab bucket, and the hydraulic oil flows into the hydraulic oil channel from the oil inlet end close to the casing 2. The turbine 4 blades can rotate efficiently under the impact of the hydraulic oil, and the rotating shaft is rigidly connected to the turbine 4 blades;

[0044] When the turbine 4 blades drive the shaft to reciprocate, the shaft drives the main gear 6 to rotate synchronously, and the main gear 6 drives the tooth plate 1 74 to reciprocate through meshing. At this time, the tooth plate 1 74 and the tooth plate 2 78 are separated, and only the tooth plate 1 74 moves;

[0045] When the oil viscosity sensor detects that the viscosity of the hydraulic oil increases, the oil viscosity sensor transmits a signal to the controller. Then, when the tooth plate 1 74 and the tooth plate 2 78 return to their original positions and the hydraulic oil no longer flows, the controller controls the output end of the telescopic rod 793 to extend, and the end of the baffle plate 77 is clamped on the inner side of the three plug plates 794 to realize the transmission of the tooth plate 1 74 and the tooth plate 2 78.

[0046] When the turbine 4 blades drive the shaft to reverse, the moving plate 10 and the filter plate 9 move into the inner side of the limiting plate 11, and the impurities in the hydraulic oil are filtered by the filter plate 9;

[0047] When the turbine 4 blades drive the shaft to rotate forward, the movable plate 10 and the filter plate 9 move out of the inner side of the limiting plate 11 and then return to their original positions. In the process of the filter plate 9 moving out of the limiting plate 11, the hydraulic oil reversely flushes the impurities filtered by the filter plate 9, and at the same time, the inner wall of the base 1 scrapes off the impurities on the surface of the filter plate 9, and finally rushes into the hydraulic oil tank with the hydraulic oil for filtering.
